U2 are an Irish rock band from Dublin formed in 1976. The group consists of Bono (lead vocals and rhythm guitar), the Edge (lead guitar, keyboards, and backing vocals), Adam Clayton (bass guitar), and Larry Mullen Jr. (drums and percussion). Initially rooted in post-punk, U2's sound grew to incorporate influences from many genres of popular music, yet has maintained an anthemic sound built on Bono's expressive vocals and the Edge's effects-based guitar textures. Their lyrics, often embellished with spiritual imagery, focus on personal themes and sociopolitical concerns. Popular for their live performances, the group have staged several ambitious and elaborate tours over their career.
